How Long Does Herpes Stay Dormant Before First Outbreak?

When a first outbreak causes symptoms soon after infection, they often begin within about 2-12 days of exposure. However, many people have mild or no noticeable symptoms, and herpes can remain latent in the body for months or years. A later recognized outbreak does not necessarily reveal when the infection occurred. Many people with HSV-2 do not know they have it, often because symptoms are absent, mild, or mistaken for another condition. During the dormant period, the virus travels along nerve pathways to establish latency in nerve clusters. Even without symptoms, the virus can still be transmitted to partners through viral shedding.
